Slight tweaks to the core formula prove fun, but Camelot barely volleys it over the net.

It’s much easier to consider Mario Tennis Open the latest home console iteration of the Mario Tennis series rather than the latest handheld title. Lacking the handheld games’ iconic RPG mode, the experience is more like a follow-up to the GameCube’s (and Wii’s) Mario Power Tennis. In and of itself, this isn’t a bad thing; however, Mario Tennis Open is thin on content and new gameplay enhancements don’t do much to vary up the experience from past iterations.
